BOOK-BINDING.

SPECIFICATION forming part of Letters Patent No. 406,476, dated July 9, 1889.

' Application filed November 20, 1888- Serial No. 291,322. (No model.)

To aZZ whom it may concern.-

Be it known that I, HENRY J. RIEs, a citizen of the United States, residing at Iowa City, in the county of Johnson and State of Iowa, have invented certain new and useful Improveln cuts in Book-Binding; and I do declare the following to be a full, clear, and exact description of theinvention, such as will en able others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

My invention relates to the art of bookbinding; and its objects are, first,to provide a durable binding which is readily placed around the book; second, to bind the book so that the leaves will remain openin any prescribed position; third, to provide a binding that will resist the wear incident to use; fourth, to dispose the book so relative to the binding that the opening and closure of the former will not affect the integrity of the latter; and, fifth, to obtain these ends with structural simplicity and economy. I accomplish these aims by the means and in the manner illustratedin the accompanying drawings, in which- Figure 1 indicates a side elevation of a book bound according to the principles of my invention. Fig. 2 shows the same in an open condition. Fig. 3 is a side elevation of the outer flexible back, and Fig. 4 is a similar View of the inner one. tion of one of the covers. Fig. 6 is a view similar to Fig. 1, in which the cover has only one slit; and Fig. 7 shows the form of cover adapted to this modification.

The same characters designate corresponding parts in the several yiews.

In the production of account-books and records subjected to constant reference a Fig. 5 is a side eleva form of binding is required that will maintain the pristine integrity of the book and not unduly tax the covers or binding. It is desirable also for this purpose that the pages will readily assume and maintain an open condition at any desired position. To these ends my invention is addressed.

The book A is secured to the flexible cover E, which has two free flaps that are adapted to be glued to theinner surface of the cover B. The cover 13 has two slits that form the walls b 11 13 between which the respective ends 0 of the back 0 and d of the outer back D are inserted and glued. These walls are tapered to sixty, forty-five, and fifteen degrees, to provide for an easy movement of the inclosed book. I also use as a modification of the same principle the cover B, having only one slit, thus making the walls 19 17*, between which the endsfd of the back D are inserted, while the ends a of the outer back 0 are glued to the outer surface of the cover B. It will be apparent that by this form of connection the book is comparatively free to open at any prescribed place and will there maintain an open condition.

Having thus fully described my invention, what I claim is- The book A, held in the flexible back E, having free flaps at either end, in combination with the concentric flexible backs G D, having, respectively, the ends 0 d, and the covers B, slitted to form beveled walls b I), wherein the ends 0 are secured, the ends. d being fastened to the outer surface of the cover 13. a

In testimony whereof I affix my signature in presence of two witnesses.

HENRY J. RIES.
